Climate change

 

  1. What is climate change?

Climate change refers to long-term changes in the Earth’s climate, particularly in temperature, precipitation patterns, and weather extremes. While Earth’s climate has naturally varied over millions of years due to factors like volcanic activity, solar cycles, and shifts in Earth’s orbit, the current changes are primarily driven by human activities, especially since the Industrial Revolution.

What is causing climate change/global warming?

 

Burning of Fossil Fuels

  • Coal, Oil, and Natural Gas: When burned for energy, fossil fuels release large amounts of carbon dioxide (CO₂), a potent greenhouse gas that traps heat in the atmosphere.
  • Power Plants, Vehicles, and Industry: These are significant sources of CO₂ emissions. Transportation alone accounts for about a quarter of global carbon emissions.

 

One of the primary products of combustion is carbon dioxide (CO₂). When fossil fuels such as coal, oil, or natural gas are burned to produce energy, carbon stored in these fuels combines with oxygen in the air, releasing CO₂ as a byproduct.

CO₂ is a greenhouse gas, meaning it traps heat in the Earth’s atmosphere. Normally, the Earth’s atmosphere contains a balanced amount of greenhouse gases that help maintain a stable temperature by retaining some of the sun’s heat while allowing the rest to escape back into space. However, the excessive CO₂ released by human activities—primarily from burning fossil fuels—enhances this greenhouse effect, trapping more heat than natural levels would.

 

Why do ākonga (students) throughout Aotearoa and globally want to go on strike from school and protest?

The School Strike 4 Climate movement, inspired by activist Greta Thunberg, began in Aotearoa in 2019 and continues today as students rally for urgent climate action. Ākonga (students) across Aotearoa, like their peers globally, strike from school to demand that leaders address the climate crisis, which they see as a significant threat to their future. Many students feel that current policies and actions are inadequate, especially given scientists’ warnings about rising temperatures, severe weather events, and ecological impacts. By striking, they raise public awareness and put pressure on governments to adopt stronger, science-based environmental policies. For many of these young people, climate action is seen as not only urgent but essential to ensuring a sustainable world for themselves and future generations. Their protests highlight their frustration with slow progress and their desire for transformative, immediate change.Striking allows students to amplify their voices, raise awareness, and pressure governments to adopt more ambitious climate policies.  

 

 

 

 

 

 

 

 

 

 

 

Clowning

Clowns wear lots of bright colours and wear big red shoes and some are black and a big red nose. they have lots of  definition hair colours some clowns have hats and some don’t some clowns are fools but most clowns are pranksters  and like to make kids happy and they like going to pratys. One thing that clowns use is balloons to give to people and most clowns like juggling and doing acrobatics and storytelling and trying to balance things that clowns like the most is unicycling.

A clown is a kind of entertainer, or performance artist, who performs physical comedy and stunts to amuse others. They usually wear grease paint makeup that hides their real face, a large wig with brightly-colored hair, and baggy, padded clothing. Clown mascot Ronald McDonald.

  • face he clown has a white-painted face with exaggerated red cheeks, a bright red nose, and large, expressive eyes outlined with bold black lines. His mouth is painted in a wide smile, extending from ear to ear, giving him a cheerful and slightly mischievous expression.
  • Hair: His hair is bright blue, curly, and voluminous, sticking out in all directions. It adds a playful and whimsical touch to his appearance.
  • Costume: He wears a colorful, oversized polka-dotted suit with vibrant shades of yellow, red, and blue. The suit is baggy and made of shiny fabric, reflecting light as he moves. Large buttons in contrasting colors adorn the front, and he has a huge bow tie around his neck in a clashing pattern.

social studies words we need to know

today In social studies we had to know some words  and then we had to do a thing about Martin Luther-King then we had to look at a video about Brown vs Board

Segregation

Separating people from one another based on ethnicity, race, gender or sexuality are just a few examples of segregation. A prime example of segregation is the divide between ‘white’ and ‘black’ people in the US, which has gone on for centuries.

Integration

The integration of alters, if it happens, does not mean an alter goes away. Integration means to combine two or more ”things” in this case alters, in order to become more effective. All the alters have their own knowledge and skill sets. When one integrates alters, that knowledge and those skill sets are combined.

Racism

the belief that different races possess distinct characteristics, abilities, or qualities, especially so as to distinguish them as inferior or superior to one another.

Discrimination 

the unjust or prejudicial treatment of different categories of people, especially on the grounds of race, age, sex, or disability. 

Non Violent Resistance

Nonviolent resistance (NVR), or nonviolent action, sometimes called civil resistance, is the practice of achieving goals such as social change through symbolic protests, civil disobedience, economic or political noncooperation, satyagraha, constructive program, or other methods, while refraining from violence and the threat of violence

Equality

They’re guarantees of equal social opportunities and protection under the law, regardless of race, religion, or other characteristics. Examples are the rights to vote, to a fair trial, to government services, and to a public education.

 

 

statistics report

Multivariate Analysis

 

Problem: 

I wonder if the median Typing speed of males is faster than the typing speed of females for all Hornby High School students..

 

Plan: 

My variables are Typing speed (wpm) and Gender.

 

We gathered the data by:

  1. Using a device, students will go on Human benchmark and select the typing speed test.
  2. Human benchmark will give students random paragraphs that students will need to fill out. Students typing speed will be reduced for inaccuracies.  
  3. Students will put their typing speed (wpm) and their gender into a spreadsheet.

 

Data:
https://docs.google.com/spreadsheets/d/1UnmU6TnOHONFKV-dkhnd4A5hlW0eE7t_N39UJwCcH1I/edit#gid=0

 

Analysis:

  • Center:
    The median typing speed of females  is 37(wpm).
    The median   _________of males is 58(wpm).

We can see that males  is faster than females by 24 (wpm).

  • Spread:

The IQR for females is 21 (wpm).

The IQR for males  is 29(wpm).

We can see that males has more variety of typing speed  than females.

 

Conclusion: 

Because the median typing speed  of males is significantly higher than females , there is enough evidence that males are faster typers than females at Hornby High School.
